For me, the perf stats are non-zero only for those OSD's that are currently writing. The others that are idle/reading show zero. (I have a recovery going on, lots of PG's being moved to two new disks. The two new ones have stats, all the others show zero.) -- linas On Fri, Nov 29, 2024 at 3:10 AM Eugen Block <eblock@nde.ag> wrote:
